ESD PRECAUTIONS AND STATIC SENSITIVE CARD HANDLING
Vocality International Ltd. observe the general requirements of BS EN 100015-1 (1992) in all matters
relating to the handling and storage of electrostatic sensitive devices (ESDs) and assemblies. We
recommend strict observance of this standard during the installation of all Option Cards.
All cards are assumed to contain at least one ESD and therefore all subassemblies containing PCBs should
be handled in the same way. Products are designed with protection components on external and internal
connectors where appropriate. User manuals, applications notes and modification instructions contain
warnings where an ESDs may become exposed to ESD. The packaging of Vocality International Ltd.
products is classified as secondary, for physical protection only.
Cards should be handled in an ESD Protected Area (EPA) using approved materials (wrist straps, bonding
cords etc) from recognized suppliers.
ESDs should always be protected by primary packaging when moving between EPAs or EPA and field
sites. Equipment containing ESDs devices in primary packaging (e.g. the metal enclosure) are moved off-
site using additional secondary packaging for mechanical protection. Within the EPA, cards should be
stored in their primary packaging in electrostatic dissipative bags.
